Disconnect from server when Alt-Tab back to PoE2 - due to Windowed Fullscreen

I had every 1/5-6 Alt-Tab events from Internet Browser to POE2 a disconnect from the server. This means hundreds of disconnects/day - very annoying.

I tried everything , after a few weeks i figured it out - it was from the Windowed Fullscreen setting. After switching to FullScreen i had 0 disconnects in last 5 days , but i have to use CTRL+ESC now to switch to browser.

Anyways, I think something weird happens when ALT-Tab-ing back to the game while in Windowed Fullscreen, maybe a lot of commands get to the Server and trigger the disconnect. Might be worth checking it out.

Thanks and GL, keep up the great work!
